Pumice and tuff are the product of violent eruptions. Rhyolite is often, but not always produced by violent eruptions, but it can also form from slow, extrusive eruptions.
Intrusive rock cools slowly from magma underground, allowing large mineral crystals to form. This slow cooling process is why intrusive rocks, such as granite and diorite, have a coarse-grained texture.
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
Gabbro typically cools slowly beneath the Earth's surface, allowing large mineral crystals to form. This slow cooling process results in a coarse-grained texture in gabbro rocks.
The size of grains in pumice can vary, but they are typically very small, ranging from less than 1 millimeter to a few millimeters in diameter. Pumice is a type of volcanic rock that forms when lava with high gas content rapidly cools and solidifies, trapping air bubbles within the rock and giving it a lightweight, porous texture.
Slowly
Pumice is the result of extremely fast cooling lava.
if a fast and expecive car yes.But a slow and ugly car no.
cool types
Cool water moves slow because the molecules are moving slow. In hot water, molecules are moving fast, thus, hot water seems to move faster than cold water at times.
Pumice is classified as a felsic, glassy, highly vesicular, extrusive igneous rock.
not a fast but slow
slow-fast-slow (Apex)
slow
fast and slow
The ocean heats up slowly due to the high specific heat capacity it possesses.
kinkajous are not very fast animals or very slow animals actually they are very slow and fast animals
